SPECIFICATION formingpart Of Letters Patent N0. 728,618, dated May 19, 1903.

Application filed November 4, 1902. Serial No. 130,069- (No model.)

To all whom it may concern:

Be it known that I, Orrro FELIX ROGGEN- KAMP, a citizen of the United States, and a resident of Seneca, in the county of Nemaha and State of Kansas, have invented new and useful Improvements in Heaters,of which the following is a full, clear, and exact descrip-' tion.

This invention relates to improvements in heaters, the object being to provide a selffeeding heater of simple construction in which corncobs or long sticks of wood may be used as a fuel.

I will describe a heater embodying my'invention and then point out the novel features in the appended claim.

Reference is to be had to the accompanying nicating therewith is afeeding-drum 3 and a heating-drum 4. The feeding-drum 3 has a cover 5,and communicating with the heatingdrum 4. is a smoke-pipe 6. At the opposite sides of the door at the front of the base or heatingbox are upwardly-extended draft-tubes 7 8.

The upper ends of these tubes are made funnel shape to receive plug-valves 9 10,by means of which the draft may be regulated. These two valves 9 10 are connected to rods 11 11, which slide in guides 12 12?, attached to the feeding-drum 3, and'the'valves'may be held as adjusted by means of thumb-springs 13 13, attached to the drum, and also attached to the rods 11 11 are finger-pieces 15.

In operation the drum 3 is to be filled with fuel-such, for instance, as corncobs or long sticks of wood standing upright. The combus'tion will take place in the base or fire-box 1, and the products of combustion will pass up through the drum 4 and the pipe 6. It is obvious that a heater embodying my invention maybe made of comparatively light metal, and therefore will be very cheap to manufacture.

Having thus described my invention, I claim as new and desire to-secure by Letters Patent- A heater comprising a base or fire-box, a feeder drum communicating therewith, a heating-drum communicating with the base,

-a draft-tube extended upward from the front end of the base, a plug-valve for said tube,

a rod extended upward from the valve,guides on the feeder-drum for said rod, and a spring on said drum engaging with said rod.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
